I solved "cannot connect to blackberry server" issue on my phone. If i remember correctly when i created appworld uer id, i chose a name and password. However when i upgraded to version i created another id but this time they asked me to choose and answer a secret question. I don't remember been asked this before but anyway im back online in appworld. This is my first blackberry thus i'm not sure if the secret question was asked because of previous id or it's new process in version 2. I'm posting this so that others who cannot connect after upgrading to new version of appworld should try this route as it it may be the solution.
